FLOORING TILE.

No Drawing.

()ur invention relates to flooring tile and while we use this termflooring tile to designate one use of the tile it is of course to beunderstood that the tile may be used on walls or other surfaces and thatwe do not wish to be limited by the term employed.

An object of the invention is to provide a tile that will be free frompot marks, which will have a hard surface that can be easily washed andthat will not allow the dirt to be readily ground into the surface andwhich will hold its original color.

A further object is to provide a tile that will have the maximum oftensile strength and flexibility so as to minimize breaking or crackingand which will have the maximum of Wearing qualities.

A further object is to provide a tile of novel composition which can begiven a desired color and which will retain the color in use.

With these and other objects in view, the invention consists in certainnovel combinations of ingredients which will now be described andhereinafter pointed out in the claim.

In making our improved tile, we mix asphalt, pitch, fiber and a coloringmatter.

The asphalt and pitch employed are brown in color when crushed or brokendown, and we find that gilsonite asphalt and vegetable pitch will breakdown brown, so that We preferably employ these materials.

Petroleum asphalt and animal pitches are black even when broken down orin powdered form, and while these materials may be used in the making ofblack tile they do not lend themselves to the making of tile of thelighter colors, and we have discovered that by employmg asphalt andpitch which will break down brown we can make the tile of variouscolttizs by the'addition of the proper coloring ma er.

Application filed January 31, 1927. Serial N0. 165,027.

Specifically stated our improved composition is as follows:

Pounds. Gilsonite asphalt 25 Vegetable pitch 25 Asbestos fiber 120Coloring matter.

.asbcstos fiber, and it is well within our invention to employ otherfiber which may be found to give good results.

These several ingredients may be mixed in standard apparatus Well knownin the art, and in order to bring about a proper mix it is necessary tomaintain a suflicient temperature, say approximately four hundreddegrees Fahrenheit, and after thorough mixing the tile may be shaped inany approved manner.

While We have set forth what we believe to be a preferred embodiment ofour invention, it is obvious that slight changes might be made in thecomposition or formula without departing fro the invention, hence we donot wish to be 1i ited to the specific pro portions set forth but desireto cover the invention as set forth in the claim.

We claim:

A tile-composition, comprising gilsonite asphalt, vegetable pitch, andasbestos fiber, in substantially the proportions of twentyfive pounds ofasphalt, twenty-five pounds :of pitch, and one hundred and twenty poundsof asbestos fiber, in which mixture coloring matter is incorporated.
